"The day I met her, I was like, 'Hey, I'll marry you tomorrow,'" he said. "She was calling my bluff. I sent her a picture [of engagement rings]. I was like, 'Do you like any of these?' She was like, 'Those are my favorite ones,' and I was like, 'Sick.'"

Davidson and Grande have become one of the most talked-about celebrity couples in recent months, particularly due to the whirlwind nature of their romance. Davidson spoke about Grande multiple times throughout his interview with GQ, mainly to assert that people only care about him because his new fianceé is a pop phenom.

"It's all bulls--t," he said. "GQ wouldn't hit me up if I didn't recently get engaged to a super-famous person."

The "Set It Up" actor also revealed that he and Grande don't have any concrete wedding plans yet — though the couple did recently move into a Manhattan apartment together, which Grande reportedly purchased for $16 million.
